Depends which SmartPC you use, I use Fatality's first edit (I have also edited it a little more so it runs better for me) Which only have 2 args, then his second edit with 3 args and then someone elses edit of his 2 with radio buttons.
If your using his second edit with 3 args they should be entered like:
2,1,1
That (I think) would be,
1st: Spend points on str
2nd: Use str prayer
3rd: Use special att
So just read which numbers are which and set your args accordingly.
